Product description:
As recognition of biochar as a powerful soil amendment in the gardening world grows, many are looking for ways to make their own at home, rather than purchase commercially sold and manufactured products.
While there are a number of traditional methods for making biochar at home, unless you have the specialist knowledge or tools, these can be dangerous as well as being damaging to the environment by releasing harmful methane gas.
That’s why we have spent the last two years developing our innovative biochar kiln - to make biochar accessible to UK gardeners in a way that is safe and sustainable.
Biochar is created through pyrolysis, which means separation by fire. Limiting the oxygen prevents most of the carbon from reacting and forming CO2, and prevents the wood from turning to ash.
In our innovative and environmentally driven design, as the wood is carbonising, the wood smoke is directed to a combustion zone and mixed with oxygen to create heat, CO2 and water vapour. The biochar you are left with is almost pure carbon and can be added to your soil, safely storing it away for hundreds of years whilst improving your soil's fertility.
Instructions for use:
Load up your kiln with your 'waste' wood of choice - we’ve found that using dry wood chips work best. Once filled, take some eco-friendly firelighters or newspaper and light it from the top. Your goal is to get the fire burning as evenly as possible, so it moves through the wood at an even rate.
Any smoke which is generated is quickly burnt off meaning no methane pollution. Smoke is flammable, so by mixing it with air you stop it from escaping.
Wood burns twice, from wood to charcoal and from charcoal to ash. Wood smoke burns orange and charcoal burns blue. The change of colour shows you that it’s time to stop the burn - this usually happens in about 45 minutes to one hour.
At this point, quench the fire with water. This stops the biochar from turning to ash and creates steam, which in turn, improves the quality of the product. When you are sure the fire is out, put your heat proof gloves on, pick up the burn chamber using the handle and tip the biochar into a bucket. Crush it up into small pieces (no bigger than an olive stone) and then it’s ready for use!
Now you have biochar that is ready to be colonised with beneficial microbes and natural plant fertiliser. The best way to use biochar is to blend it with finished compost, or to add it to your home composter and wait for the biochar amended compost to be produced. However, there are 55 uses of biochar, not just for soil, check out our podcast episode with Roots and All to hear about some of these fascinating uses.
